The current tree (since november 2004) doesn't contain the matrix
wrapper code anymore, it has been moved to a separate "project". So now you have to get both subdirs as described below.
svn co http://svn.mech.kuleuven.be/repos/actsens/software/bfl/trunk bfl-trunk svn co http://svn.mech.kuleuven.be/repos/actsens/software/wrapper/matrix/trunk/ matrixwrapper-trunk
Installation instructions are found in the INSTALL file or the Getting Started Guide.
